Beijing has officially entered the influenza high-season, slightly later than previous years. Recently, Dr. Li Tongzhen, the Director of the Infectious Disease Department at YouAn Hospital, warned that the prevailing influenza virus is mainly the H1N1 subtype. Fortunately, individuals with normal immune functions can usually recover from the disease on their own. However, the authorities urge citizens to maintain vigilance, receive timely vaccinations, and seek medical attention as soon as symptoms appear to facilitate timely antiviral treatment.
